Yes, you can block other members from contacting you. Blocked Users are not able to contact you and no messages will be forwarded to your in-box.
Every user on SingleMuslim.com has the option to block any other user that they do not wish to have further communication with. SingleMuslim.com will not intervene in any user's decision to use the "Block User" feature. We will always respect the decision of the user and will not contact them; to forward any further communications to them, to ask them to unblock you, or to question their reasons for blocking you. Blocking another user is a manual process and can not be done by accident.
You can unblock blocked users by selecting Blocked Users from the main menu.
